20–B1.2k apply Newton’s first law of motion to explain, qualitatively, an object’s state ofrest or uniform motion

20–B1.3k apply Newton’s second law of motion to explain, qualitatively, the relationshipsamong net force, mass and acceleration

20–B1.4k apply Newton’s third law of motion to explain, qualitatively, the interactionbetween two objects, recognizing that the two forces, equal in magnitude andopposite in direction, do not act on the same object

20–C1.6k predict the mass of a celestial body from the orbital data of a satellite in uniformcircular motion around the celestial body

20–C1.7k explain, qualitatively, how Kepler’s laws were used in the development ofNewton’s law of universal gravitation.

explain that work is atransfer of energy andthat conservation ofenergy in an isolated

system is afundamental physicalconcept.

20–C2.1k define mechanical energy as the sum of kinetic and potential energy

20–C2.3k analyze, quantitatively, kinematics and dynamics problems that relate to theconservation of mechanical energy in an isolated system

20–C2.4k recall work as a measure of the mechanical energy transferred and power as the rateof doing work

20–C2.5k describe power qualitatively and quantitatively

20–C2.6k describe, qualitatively, the change in mechanical energy in a system that is notisolated.

describe theconditions thatproduce oscillatorymotion

20–D1.1k describe oscillatory motion in terms of period and frequency

20–D1.2k define simple harmonic motion as a motion due to a restoring force that is directlyproportional and opposite to the displacement from an equilibrium position

20–D1.3k explain, quantitatively, the relationships among displacement, acceleration, velocityand time for simple harmonic motion, as illustrated by a frictionless, horizontalmass-spring system or a pendulum, using
